ux(inertia): preserve scroll and filter state when navigating back from Resource details

[wyzuk]

Description

When navigating through subjects/nodes (especially after expanding to SSC + HSC levels) and clicking into a specific resource view, pressing the browser's Back button or returning to the chapter list resets the view and scroll position.

Expected Behavior

Users should be returned to their exact scroll position and active chapter node filters.

Suggested Fix

Use Inertia's remember property or preserveScroll: true / preserveState: true on resource back-links and filter components:

<Link :href="route('subjects.show', subject.id)" preserve-scroll preserve-state>
  ← Back to Subject
</Link>

Thanks for the suggestion @wyzuk

Closing this issue as it does not apply to the current architecture:

1. Native History Navigation: The back button on the Resource page uses window.history.back(), which natively preserves the browser's scroll position and history state for the previous page.
2. No Client-side Filter State: Subject and chapter navigation is handled via discrete server-side routes (/{subject:slug}/{path}) rather than client-side expandable tree or filter state.
3. Inertia preserveState Scope: Applying preserveState across different page components (from /resources/{id} to subject/node pages) is not applicable in Inertia since component state is page-
   specific.
